2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 & 1.98

The prior art discloses a wide variety of carrying cases for laptop computers, however, these existing designs are overly complicated and focus heavily on proposing varying dimensions in laptops, notebook computers, and laptop accessories as well. The present invention focuses on shielding the user from harmful EMF including but not limited to RF microwave radiation and heat, while serving at the same time as a simple, lightweight/compact, protective, attractive, and sturdy case in which the user can carry a laptop. The invention also makes cellular phones more readily and safely available by being able to store the phone on the case with a Velcro® accessory strip when placed in a Cellular Shield or Cellular Shield Holster via the accessory Velcro® strip.

Prior art patents of interest in addition to applicant's previously cited U.S. Pat. Nos. 6,515,223 and 5,367,307 include U.S. Pat. Nos. 7,036,642; 6,349,825; and, 5,124,899.

SUMMARY OF INVENTION

The present invention shields the laptop user from the harmful heat and the EMF generated including but not limited to RF microwave radiation emitted by a laptop particularly when being used on the user's chest or lap regions and also serves as a lightweight carrying case and base support for the laptop computer. The shielding device folds over itself to form the carrying case and protects the laptop or notebook when stored therein. The case has open sides and a top to facilitate use. With the open top and partially open side regions, cooling is facilitated after the apparatus is turned off or if it is mistakenly turned on.

The product of this invention includes a substantially rectangular main body portion having sewn insulating sections along the internal nylon face thereof and an external sewn face made of leather or similar materials. The main body portion is manufactured using the shielding technology disclosed in U.S. Pat. Nos. 6,515,223 and 5,367,309 to Tashjian. Essentially, the body is rectangular in shape and comprised of conductive fabric centrally positioned against a non-conductive plastic, then rolled up onto itself for several inches inwardly on all four sides. This permits a larger functional effective virtual shielding area while having a physically smaller acting/functioning area. This process allows for a minimum of three to five times the functional surface area ratio, (as was also previously stated in applicant's patent '223) increasing the actual shielding effectiveness many fold while physically displaying a smaller more compact working area. The EMF “sees” the shielding area as a larger effective area then it actually is. This shielding structure can be used in laptop cases, cell phone cases, or pockets for carrying cell phones.

An optional magnetic field shielding layer may be used in the laptop carrying case instead of the perforated metal sheeting layer. This shielding layer comprises thin plywood laminate sheeting wrapped in a magnetic field shielding material which provides a durable lighter structure. The shielding layer would be mounted internally on each side of the case.

On all size cases, handles are mounted on both ends of the main body of the case to fold over against one another or be used as a single handle. Velcro® tabs and strips are mounted on the external main body sides. The main body is flexible in two linear regions allowing three mobile sections only due to the rigidity of the three Luan or similar material sheets ˜¼″ in thickness sections mounted within the casing. The body folds over itself to form a carrying case with a base and two sides. The case is secured by fastening Velcro®/leather elastic straps having mounted Velcro® tabs to the Velcro® tabs on the upper and side portions of main body. The TCS Holster case may be readily mounted on the external face of the carrying case via a midline vertical accessory Velcro® strip for purposes of carrying a cellular phone in the holster or for storing a Cellular Shield (U.S. Pat. No. 6,515,223), as well as, optional detachable accessories like a pen/pad organizer, et al. External risers may also be provided on the external face as well as internal risers on which to place the laptop when the case is opened. Optionally, a pivotal mouse pad may be mounted to one of the internal faces to swing outwardly therefrom for use.

The present invention protects the user from the thermal emissions and EMF including but not limited to RF microwave radiation emitted from a laptop (i.e. WI-FI, wireless, LAN/internet, etc.) when using the apparatus on your lap or chest regions. The user simply disengages the two top and two side-fastening straps on the carrying case and then opens the carrying case, which now becomes a firm/rigid shielding mat/base on which the laptop rests. The four straps can stay attached to the mat on the one side for easier access and reattachment when needed again for reattachment. The shielding mat is also used as a buffer and thermal shield between the user and the laptop. In one preferred embodiment, ¼″ Luan, plywood, or similar material is formed in three sections with an optional magnetic shielding material bonded onto or around it, within the insulation to provide a magnetic shielding component in both the open and closed positions.

In addition, due to its unique design, the present invention allows for better and more efficient cooling once the laptop is shutdown or is in a standby mode or even accidentally turned on and placed in the case. This feature can add months or possibly years to the lifespan of a computer and also improves battery performance. Overheating and slower cooling can accelerate the overall aging process of the internal electrical components of the computer. This process is cumulative particularly if the laptop is accidentally turned on after being stored in the case. One can still easily see and hear it turned on while it is stored and protected in the case.

The present invention is available in several predetermined sizes to support larger or smaller laptops. There are generally about four conventional laptop sizes, all of which can be accommodated

Accordingly, an object of this invention is to provide a new and improved laptop shield carrying case and an associated cellular shield holster for cell phone storage.

Another object of this invention is to provide a uniquely constructed laptop shield that folds into a compact and protective carrying case.

Another object of this invention is to provide a new and improved laptop shield including a plywood laminate wrapped in a optional magnetic field shielding material and positioned in a unique laptop carrying case.

A further object of this invention is to provide a new and improved laptop shield carrying case which includes a main body of conductive material centrally positioned against a non-conductive plastic rolled upon on itself on all four sides to provide a larger than actual virtual shield.

A still further object of this invention is to provide a flip version cellular shield case and alternatively a cellular pocket shield.

A more specific object of this invention is to provide a new and improved laptop shielding carrying case for protecting against heat and EMF radiation wherein the main body includes three Luan or similar material sheeting sections with magnetic shielding material bonded or around it to shield the laptop magnetically and a virtual electro-shield of conductive material and further including Velcro® affixed portions on the external faces for securing the sides into a carrying case and for mounting a cellular shield holster. Also inside the casing is a micro-bubble type plastic foam sheathing or similar material for the thermal shielding component, as well as, protection against shock/external vibrations and a Faraday cage compartment to store credit cards, ATM cards, etc.

fasteners

33 and 34 which engage

pads

13 and 14 to secure the sides of the case 8.

FIG. 2 discloses the internal face 11 b of the case 9 in a fully open position for shielding a laptop computer 8 ready for loading in the case 9. The main body 10 is folded along the

lines

71, 72 to form the two

sides

73 and 74 and the base 75 to hold the computer 8. The internal risers 76 are mounted on the internal faces 73, 74. The cylindrical or rectangular risers 76 are intended to space the laptop 8 from the

faces

73, 74 for cooling purposes. Optionally, risers 77 may be affixed or removably mounted to the base 75. A mouse-pad 80 may be pivotally mounted with element 81 to the edge 82 so that it can pivot outwardly for use. The side holding straps 15 attach and fold as indicated when the case 9 is in an open flat position. Elastic holders 78 may be provided for holding pens, magnetic risers etc. A storage box 79 may be included on the base 75 to store external risers.

FIG. 3 discloses a laptop computer 8 which is positioned on risers 76 on the case 9. The mouse pad 80 pivots outwardly from the case 9 to facilitate use with the computer 8. The case 9 is positioned on the incline for ease of viewing.

FIGS. 4 a, 4 b schematically depict the use of the laptop shield 9 in respective opened flat 23 and closed inclined positions 24 with the user 21 sitting on a chair 22. The laptop 8 is flat with respect to the carrying case 9 in FIG. 4 a and at an angle in FIG. 4 b with the closed case 9. The base 35 provides the incline which facilitates the user's view of the keyboard and computer 8.

FIGS. 4 c-4 f show the use of the laptop shield 9 in a supine position. FIG. 4 c shows the case 9 in a closed position while FIG. 4 d shows the case 9 in an open flat position. FIGS. 4 e and 4 f show the main body 10 a, 10 b of the case in a folded position. Folding the case 9 about the user as in FIGS. 4 e and 4 f minimizes any remaining magnetic field energy component by channeling whatever is not reduced around the user's body.

FIG. 5 is a perspective view showing the laptop shield carrying case 9 with a TCS holster 50 having a cell phone 25 mounted therein. The holster 50 is secured to the main body of the case 9 by the Velcro® accessory strip 53. The Velcro® strap 51 secures the cell phone 25 within the holster 50.

FIG. 6 is a perspective view of the laptop shield/case layered components. A thin plywood laminate (luan) sheeting 26 or a hollowed out sheet of plastic paneling or similar material (not shown) engages spacers 28 on a thin magnetic field shielding sheeting 27. A secondary thin magnetic field shielding material 29 is wrapped about the plywood 26 forming a box shaped configuration 30 as shown in FIG. 6 b.

FIGS. 7 a-7 c shows the assembly of electro-component shielding aka TCS for the laptop case 9 wherein vertical shielding is employed. FIG. 7 a shows conductive fabric 54 mounted with plastic sheeting 55. In FIG. 4 b the horizontal edges 55 a-55 b folded inwardly shrinking the shield size. In FIG. 7 c, the

edges

55 c and 55 d are folded downwardly shrinking the shield to the size of a cell phone 25. The approximate EMR mitigating effect causes 50-60% deflection/reflection via a type of “parabolic effect”. The remaining 40-50% is absorbed or cancelled out via a “self-ground” phenomenon.

FIG. 8 shows the assembly of the laptop shield with case-layered components. The outside face 11 a of leather or nylon has a flexible ˜⅛″ plastic type Styrofoam sheet (or similar material) 31 mounted thereto and then an optional luan shielding sheet 26 in three sections, and a flexible ˜⅛″ plastic type Styrofoam sheet 34. A metal electric shielding sheet 35 is mounted to the luan sheet 26 and then a further plastic Styrofoam 32 sheet is mounted thereto. The inside surface comprises a sports/ballistic nylon sheet 33 (or similar materials). This layered assembly forms the laptop shield carrying case 9.

The above shielding assembly, once completely rolled up/formed, may also be used by wrapping or bending the two sides and bottom rolled edges around at 90° and fitted inside TCS Holster casing along the inside of its both sides and bottom regions. This additional step would allow for an even smaller, more compact, AP (Antero-Posterior) portrait/view while still maintaining its overall shielding effectiveness/performance.

FIG. 9 a is a flip version of the cellular shield case/holster 60 in an open position. The cell phone (not shown) slides into the case 60 in the direction of the arrow where it is retained therein. The shielding is contained in the flipping section 62. This section pivots over the case 60 to enclose a cell phone. The side of this case is indicated as 61. Holes 63 in the covering material permit improved audio transmission. 60 a direction is in the talking position (closed position) and 60 b direction is in the storage position (opened position). The shielding is as previously discussed.

FIG. 9 b shows the shield/holster 60 in a completely folded backward and down stored position over a belt 64 protecting the user's body.

FIG. 10 discloses a box version 65 of the cellular shield case wherein

end portions

67 a, 67 b, of the shield 66 are bent at right angles and the shield 66 is positioned in the case 65.

FIG. 11 shows the

cellular shield pocket

80 a and 80 b which is placed in an apparel pocket 80 c to provide cell phone shielding. The arrangement provides shielding when a cell phone is placed in a pocket for storage and/or when used with a head set. One simply drops the cell phone into a shield pocket opening 81 to protect the user's body. The shield 80 can also be dropped in existing cell phone cases.

FIG. 12 shows the operation of the laptop shield case 90 in the open position with a flip side 91 which protects a fetus in utero 92 from radiation emitted by the laptop 93 during operation by an individual 94.

It is to be noted in the above description that a Faraday Cage Compartment FIG. 2 78 a, in the CAVE™ case can be safely used for storage of credit cards, ATM cards, etc. This can reduce electronic stealing of the personal information stored on the cards via the new remote blink technology that is currently being deployed in today's market.

A further advantage of the CAVE™ Laptop Case/Shield is that the conductive material alone can be used without any folding with the non-conductive material to still maintain a substantial EM shielding barrier due to the unique design of the case. The case design incorporates the additional EM mitigating elements of distance, redundancy, and increased surface working area.

The above aforementioned Shielding Apparatus 97 (a.k.a. The Cellular Shield™, a.k.a. TCS™) can also be implemented inside already existing cellular phone and laptop computer cases and sleeves by simply varying its overall size and/or shape, protecting the user 99 see. FIGS. 13 a and b and 14 a-c. Here, Risers 98 are also implemented, raising the laptop computer 96 slightly, as to not obstruct intake airflow needed for its cooling system when it is placed on top on case/sleeve 95.

While the invention has been explained by a detailed description of certain specific embodiments, it is understood that various modifications and substitutions can be made in any of them within the scope of appended claims, which are intended also to include equivalents of such embodiments.
